Designed for next-generation compact thermal systems, this 5.8mm F1.2 athermalized LWIR lens utilizes premium chalcogenide glass to deliver excellent infrared transmission in a lightweight profile. Its advanced optical structure is specifically optimized for high-resolution 640×512 detectors with a 12μm pixel pitch, ensuring sharp imagery without spatial distortion. The fixed-focus athermalized design eliminates focus drift during rapid temperature changes, while the standard M18×0.5 threaded interface with a precise 14mm BFL offers a secure, plug-and-play installation for space-limited UAV payloads, portable scopes, and security nodes. Engineered for durability, the rugged metal housing ensures long-term stability in field operations.
